EV2770-L-00A

The EV2770-L-00A is an evaluation board designed to demonstrate the capabilities of the MP2770, a highly integrated, flexible, switch-mode battery charge management and system power path management device. It is designed for single-cell Li-ion and Li-polymer batteries used in a wide variety of portable applications.

The MP2770 has an integrated IN to SYS pass-through path to pass input voltage (V_IN) to the system, even while charging is disabled. When V_IN is present, the device operates in charge mode. The MP2770 manages the input power and meets the majority of the system’s power demand using its integrated input current limit (I_{IN_LIM}) and V_IN regulation function.

If V_IN is not present, the MP2770 enters boost mode to power IN or SYS from the battery. The IC can flexibly configure the charging and boost parameters via the digital interface. These configurable parameters include the input clamp voltage, I_{IN_LIM}, charge current (I_CHG), charger full voltage, boost output voltage (V_BST), and current limit (I_LIMIT).

The EV2770-L-00A supports 5V to 15V input sources, including standard USB host ports and wall adapters with fast charging capabilities. The EV2770-L-00A supports boost output operation by supplying 4.3V to 16V of voltage with a maximum 3.65A load.
